COMBINED CLEANING AND INSECTICIDE APPARATUS John A. and. Ilion, N. Y. Application September 10, 1947, Serial No 773,161

- 2 Claims. (01. 43-147) This invention relates to a combined cleaning and insecticide apparatus.

An object of this invention is to provide a device which in one machine will be capable of performing the cleaning, spraying and dusting of walls and/or equipment about a dairy barn, stable or the like.

Another object of this invention is to provide apparatus of this kind which is so constructed and arranged that the component parts thereof may either be used separately or together.

A further object of this invention is to provide in a liquid spray system, an improved vaporizing means, so that the liquid insecticide or cleaner may be discharged in a regulated vapor or spray.

A further object of this invention is to provide apparatus of this kind which will permit the mixture of a powdered insecticide with a liquid which may also contain an insecticide so that the liquid spray may serve as a vehicle or carrier for the immiscible powder in order that the latter will eii'ectively adhere upon drying of the liquid spray to the surface of the desired parts.

A further object of this invention is to provide apparatus of this kind which is mounted on a common base and may be secured to a mobile chassis or the like so as to make the device easily portable.

with the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a side elevation partly broken away of a combined cleaning and insecticide apparatus constructed according to an embodiment of my invention,

Figure 2 is a top plan view thereof,

Figure 3 is a vertical section partly broken away taken on the line 33 of Figure 1,

Figure 4 is a vertical section taken substantially on the line 44 of Figure -2,

Figure 5 is a longitudinal section through the mixing chamber of the apparatus,

Figure 6 is a fragmentary horizontal section taken through the discharge port and nozzle of the liquid containing tank,

Figure 7 is a longitudinal section taken through the discharge nozzle of the device, and

Figure 8 is a vertical section taken on the line 88 of Figure 7..

Referring to the drawings, the numeral Ill designates generally a device for spraying a liquid 2 from a single source of air pressure supply so that either the liquid or the powder may be sprayed alone or the liquid and powder may be combined in a single spray.

In modern farms sanitary regulations of the State require that certain sanitary standards be maintained. In order to maintain the barn up to the standards required, it is necessary at frequent intervals to clean the walls and other structure in the barn and spray the structure with a suitable insecticide. The work at the present time entails the necessity of hiring certain persons for cleaning the structure and others to come at a later date for spraying the insecticide. It is an object of this invention to provide one unit which is capable of doing both of these jobs and can do these jobs in an approved manner by uniting the cleaning solution and the insecticide powder in a single spray when desired.

The combined cleaning and insecticide apparatus III is formed of an elongated substantially rectangular base I l on which the cleaning and insecticide spraying apparatus is to be mounted. An air compressor I2 is mounted on one end of the frame H and is adapted to be connected to an electric motor 14 or other suitable driving means for operating the compressor.

cleaning solution and a powder insecticide spray closed by a nut or cover 2|.

A compressed air tank I5 is suitably mounted on the base ll closely adjacent to the compressor l2 and may be supported above the base II by suitable supporting structure IS. A pipe I! is connected between the compressor l2 and the air tank ii for forcing air under pressure into the tank.

The pipe or tube I1 is connected at the upper end of the tank l5 by a suitable coupling or elbow as l8. The tank [5 is constructed to contain air under the required or necessary pressure. A liquid tank I9 is mounted on the frame ll adjacent the air tank l5 and is of a suitable size for supporting a large amount of liquid therein.

The tank I 9 is formed with an upwardly extending-tube 20 thereon which is adapted to be The liquid may be admitted into the tank through the opening or tubular connection 20 at the upper end there-' tanks I5, l9, and 24. A pipe or tube 28 is fixed between the lower end of the air accumulator tank I5 and the bottom end of the liquid tank l9. Suitable couplings as 29 and 30 are provided on the pipe 28 for their connection to the tanks. A valve 3I is fixed along the length of the pipe 28 preferably adjacent its junction with the tank I5 for opening or closing the air passage between the two tanks. Y

As the material to be contained in the tank I9 is preferably formed of a liquid, cleaning liquids in such use frequently require much agitation to prevent the settling of suspended material therein. It is for this reason that the air pressure line from the tank I5 is connected to the bottom of the liquid supporting tank I9. As air under pressure is admitted to the bottom of the tank I9, the air will bubble upwardly through the liquids thus causing the necessary'agitation.

A pipe or other suitable tubular connection 32 is fixed between the air pressure tank or accumulator I5 and the lower end of the powder receptacle or tank 24. A valve 34 is interposed along the length of the pipe 32 preferably adjacent the tank I5 for controlling the fiow of air pressure from the tank I5 to the receptacle 24. A pipe 35 is connected between the mixing chamber 21 and the air pressure tank I5. A valve 36 is connected along the length of the pipe or tubular connection 35 preferably adjacent the tank I5 for controlling the air pressure from the tank I5 to the mixing chamber 21.

A discharge port or passage 31 is provided on the lower end of the tank I9 from which the liquid may be discharged. A valve 38 is connected to the outer end of the discharge port 31. A T-fitting as 39 is threadably secured to a coupling 40 on the valve 38 through which the liquid is adapted to be passed. As it is discharged from the tank I9 a reduced diameter coupling member H is threadably engaged in the coupling member 40 between the T 39 and the valve 38. A discharge nozzle member 42 is threadably engaged on a union 44 between the coupling member M and the discharge nozzle 42-; A discharge nozzle 42 is of such a diameter that it is spaced from the inner walls of the horizontal or cross arms of the T member 39.

The discharge nozzle 42 is removably attached to the discharge port of the tank I9 so that various nozzles 42 of the desired spray capacity may be used. I

A pipe or tubular connecting, member 45 is connected to one end of the T member 39 and to the air pressure tank I5. A valve 46 is interposed along the length of the pipe 45 between the T fitting 39 and the tank I5, preferably adjacent the tank I5. Another pipe or tubular connecting member 41 is connected between the other end of the T fitting 39 and the mixing chamber 21. The discharge nozzle 42 is disposed along the air line formed by the pipes 45 and 41 substantially 41 is adapted to pass around the side edges of the discharge nozzle 42 and will aid in drawing the liquid spray therefrom.

A discharge opening 48 is formed on the upper end of a irustroconical cap 49 on the upper end of the receptacle 24. The opening 48 isformed 'at the apex of the convergent end of the cap 49. A coupling member 59 is threadably engaged in the discharge opening 48 and a valve 5| is securgd on the upper end of the coupling member 5 A suitable pipe or conducting member 52 is connected between the valve 5| and the mixing chamber 21. The air pressure line 32 connected to the powder tank 24 is connected to the lower end thereof and preferably the lower end of the tank 24 is formed with downwardly convergent inner walls 54 so that the air under pressure is admitted at the extreme bottom of the tank. In the mixing chamber 21, the discharge pipes or tubular connections from the various tanks are merged together. The discharge pipe or tubular connection 52 from the powder tank 24 engages through the one end wall of the mixing chamber 21 and is connected to the inner end of the pipe 41 through which theliquid discharge is admitted to the mixing chamber. The terminal ends of the tubular connecting members 52 and 41 are joined and communicated together for final discharge and mixture thereof at this point as indicated by the numeral 54 in Figure 5.

The air pressure line 35 which connects directly between the air pressure tank I5 and the mixing chamber 21 is engaged through the wall of the mixing chamber and is terminated closely adjacent the terminal end of the pipes 52 and 41 within the chamber 21.

The opemng 54 at the juncture of the connecting means 41 and 52 is disposed substantially at right angles to the axis of the end of the air pipe 35 and is spaced forwardly therefrom. The disposition of the inner end of the tubes 35, 41 and 52 within the mixing chamber 21 is such that the air under pressure admitted through the pipe 31 will induce the fiow of the material in the other pipes and its passage over the end thereof.

A coupling member 55 is threadably engaged in the small and 5 5 of the mixing chamber 21. The mixing chamber 21 is formed of an arcuate end wall 51 through which the pipes described above are adapted to engage. Forwardly divergent inclined" side walls 58 of the chamber 21 are terminated in the reduced end 56 thereof.

The substantially triangular space between the convergent walls 58 forms a converging funnel through which the material admitted to the chamber 21 must pass as it is discharged from this mixing chamber.

Such a reduction and converging of the material will substantially increase the mixing of the materials as they are discharged.

Preferably an elongated flexible tube or hose 59 is secured to the coupling member 55 at the discharge end of the mixing chamber 21. The mixed materials are adapted to be carried through this pipe 59 in their mixed condition prior to being discharged onto the wall or other structural material on which the cleaning or insecticide material is to be disposed.

A valve 50 is secured on one end of the flexible tube 59 and a final discharge nozzle BI is connected to the other side of the valve 60. The discharge nozzle BI is provided for discharging the entire mixed materials or selected material as a venturi. The air through the pipe 45 and from the apparatus I0.

The discharge nozzle BI is formed with a tubular end 62 which is adapted to be connected to the valve 60 and a flattened discharge end 62. The end 64 is formed of a pair of fiat walls 65 spaced apart along the length thereof and connected together by outwardly divergent side walls 66 In the use and operation of this combined cleaning and insecticide apparatus, when it is desired to use the device for spraying cleaning material only, the valves 3|, 38 and 46' are opened while the remaining valves are left in the closed position. The air under pressure 'will flow through the pipe 28 into the tank 19 for agitating the liquid therein and placing the liquid under pressure. The pressurized liquid is then discharged from the tank l9 through the valve 38 and the discharge nozzle 42 into the air line 41. Thence the liquid now a spray is admitted to the mixing chamber 21 and may be forced outwardly through the flexible tube 59, the valve 50 when opened, and the discharge nozzle 6|.

The powder may be dispensed alone from this apparatus by opening the valves 34, 5| and 60. The air will travel through the pipe 32 up through the tank 24 and force the powder into the mixing chamber 21 through the pipe 52, thence :lluough the flexible tube 59 and discharge nozzle The air under pressure may be admitted into the mixing chamber 21 through the pipe 35 and valve 36 when the liquid or powder is being dispensed alone or when the liquid and powder are being mixed together.

I do not mean to confine myself to the exact details 01' construction herein disclosed but claim all variations falling within the purview of the appended claims.

Having thus described my invention, what I claim is: n

1. A combined cleaning and insecticide spraying device comprising air pressure means, a cleaning liquid tank connected to said pressure means, a powder tank connected to said pressure means, a mixing chamber connected to said pressure means, means connecting said liquid and powder tanks to said mixing chamber, said latter named means projecting into said chamber in a manner such as to unite the liquid and powder prior to 6 discharge of the liquid and powder into said chamber, the connection between said pressure' means and said chamber projecting into said chamber in a manner such that the air stream from said latter means will intersect the combined liquid and powder streams on an oblique angle, and a spray means connected to said chamber.
